ZW32-12J戶外柱上開關附自動重合閘及計量變壓器
簡短的介紹:
The ZW32-12J is an intelligent pole-mounted sectionalizer specially designed for 10kV outdoor distribution networks. It integrates three core functions: auto-reclosing, fault isolation, and energy metering. 採用真空作為滅弧介質, it features strong breaking capacity, excellent insulation performance, and high adaptability to harsh environments. This device can automatically identify and cut off short-circuit faults, and restore power to non-faulty areas after a successful reclose. Equipped with metering transformers, it accurately measures electricity data. Widely used in urban and rural distribution networks, 工礦企業, new energy stations and other scenarios, it is a key device to realize distribution automation, reduce power outage time and improve power supply reliability.
一、产品描述 (產品描述)
ZW32-12J 柱上分界开关是 12kV 户外柱上配电系统的智能化核心设备。该产品采用真空灭弧技术，彻底避免了 SF6 气体泄漏的环保隐患，符合全球低碳發展趨勢。其核心设计在于 **“分界 + 重合 + 计量”** 的三合一功能：
- 智能分界与保护：作为配网线路的 “守门人”，它能精准判断故障区段。当线路发生短路或接地故障时，开关迅速分断隔离故障点；故障切除后，自动进行重合闸尝试，若故障消失则成功恢复供电，实现非故障区域的快速供电恢复，最大程度缩小停电范围。
- 自动重合功能：配備高性能彈簧操動機構，動作靈敏可靠，机械寿命长。可支持多次自动重合，有效应对瞬时性故障（如雷击、树枝搭接等），无需人工现场操作，极大提升了供电可靠性。
- 內建計量互感器：产品集成了专用的电流、电压计量互感器（CT/PT），无需额外安装计量装置，即可实现对用户或线路的电能计量、负荷监测及远程抄表功能，为电力运营管理提供精准数据支持。
产品整体防护等级达 IP67，可在 – 40℃至 + 60℃的极端环境下稳定工作，适应高海拔与重污染地区，广泛用于 10kV 城乡配网主干线、分支线路改造、光伏 / 风电等新能源项目的并网接入点，以及工矿企业的专用配电回路保护。
Description
The ZW32-12J is the intelligent core device for 12kV outdoor pole-mounted power distribution systems. 採用真空滅弧技術, it completely eliminates environmental pollution from SF6 gas leakage, 順應全球低碳發展趨勢. Its core design lies in the all-in-one function of “Sectionalization + Reclosing + 測光”:
- Intelligent Sectionalization & Protection: As the “gatekeeper” of distribution lines, it can accurately identify fault sections. When a short-circuit or ground fault occurs on the line, the switch quickly isolates the faulty point. After fault clearance, it automatically attempts reclosure. If the fault disappears, power is restored, achieving fast power recovery for non-faulty areas and minimizing outage scope to the greatest extent.
- Auto-Reclosing Function: Equipped with a high-performance spring operating mechanism, it features sensitive and reliable action with a long mechanical life. It supports multiple automatic reclosing attempts, effectively handling transient faults (such as lightning strikes, branch contacts), eliminating the need for on-site manual operation and greatly improving power supply reliability.
- Integrated Metering Transformers: The product integrates dedicated current and voltage metering transformers (CT/PT). Without additional metering devices, it enables accurate energy metering, load monitoring, and remote meter reading for users or lines, providing precise data support for power operation and management.
With an overall protection level of IP67, the product can operate stably in extreme environments from -40℃ to +60℃, adapting to high-altitude and heavily polluted areas. It is widely used in 10kV urban and rural distribution network trunk line renovation, grid connection points of new energy projects such as PV/wind power, and dedicated distribution circuit protection of industrial and mining enterprises.
